Definitions
- the present invention relates to a haptic apparatus that provides a tactile stimulus for users.
- Terminal apparatuses using haptic devices using vibration, an electric stimulus, mechanistic deformation, a piezoelectric element, and the like, and services using the haptic devices are being developed.
- the haptic devices are designed assuming, as a base, a specific gripping shape in consideration of a positional relationship of an actuator, an electrode, and the like, mechanistic efficiency, and the like for an effective exertion of performance.
- an apparatus that is provided with vibrators at one end and the other end of a casing, lets a user place a thumb of a left hand on the one end side and a thumb of a right hand on the other end side to grip the casing, and provides the user with a rotational tactile force sensation (see Patent Literature 1).
- the above-described technique has a configuration in which the tactile force sensation is most effectively generated by lightly gripping vicinities of left and right ends of the casing with fingertips.
- the degree of freedom of grip is high, the casing is often not gripped as intended by a designer. If a different place is gripped, the tactile force sensation of the user will be reduced. Therefore, measures have been taken such as guiding how to grip by the external shape and the like of the casing (see FIG. 15 and Patent Literature 2).
- Patent Literature 1 International Publication No. WO 2017/115729
- Patent Literature 2 Design Registration No. 1571053.
- a human hand can grip an object by adapting to various shapes, and often grips at a place not intended by the designer even if the object has the external shape for guiding like the above-described technique. Since the state of a grip portion tends to be hidden in a palm, it is not easy to check an actual practice or a recorded video of another operator in order for the operator to grasp a correct grip method. When an instructor or the like gives guidance, it is not easy to check the gripping state of the operator. For this reason, for example, it has been necessary in the past for an instructor familiar with characteristics of a haptic apparatus to give guidance by touching fingers of each operator, and there was a problem that it was not easy to guide how to grip the casing of the haptic apparatus.
- Embodiments of the present invention have been made to solve problems as described above, and an object is to make it possible to more easily guide how to grip a casing.
- a haptic apparatus includes a casing that can be gripped, at least one sensor that detects contact of a finger of a user who grips the casing, a determination unit that determines whether sensor information on a contact position of the finger detected by the sensor matches preset reference position information, a notification unit that notifies at least one of an indication indicating that the contact position of the finger is shifted from a reference position when the sensor information does not match the reference position information and an indication indicating that the contact position of the finger matches the reference position when the sensor information matches the reference position information, and a tactile stimulus generation unit that provides a tactile stimulus for the user gripping the casing.
- the plurality of sensors are provided in the casing, and the determination unit uses, as the sensor information, combination of detection results of contact of the finger by the plurality of sensors or a value derived by a specific relational formula from the detection results of contact of the finger by the plurality of sensors.
- the senor may be of a capacitance type.
- the tactile stimulus generation unit may be composed of an actuator that generates mechanical vibration.
- the actuator provides a tactile stimulus, for example, by asymmetrical vibration.
- at least one of electrodes constituting the sensor is preferably connected to an extrapolation unit of the actuator so as to be common or electrically equipotential.
- the tactile stimulus generation unit may be composed of electrodes that provide an electric stimulus to a finger.
- at least one of the electrodes constituting the sensor is preferably connected to the electrodes constituting the tactile stimulus generation unit so as to be common or electrically equipotential.

- the tactile stimulus generation unit 105 provides a tactile stimulus for the user gripping the casing 101 .
- the tactile stimulus generation unit 105 is composed of, for example, an actuator that generates mechanical vibration.
- the actuator provides a tactile stimulus, for example, by asymmetrical vibration.

- the electrodes 121 , 122 , 123 , 124 , 125 , 126 , and 127 detect, for example, capacitance caused by the contact of the finger of the user gripping the casing 101 .
- the electrode 121 is formed on a surface side of the casing 101 and can be contacted by a finger 106 .
- an electrode 121 a is formed on a backside of the casing 101 , and the finger 106 may not contact the electrode 121 a.
- the electrodes 121 , 122 , 123 , and 124 are connected to a controller 131 , as shown in FIG. 6 .
- this state is determined by a determination unit included in the controller 131 .
- a determination result thereof is, for example, displayed on a visual display device 141 serving as a notification unit by control of the controller 131 .
- the determination result is output as sound from a speaker 142 serving as a notification unit by control of the controller 131 .
